Detailed Answer

In New York, you can pursue a diminished market value (DMV) claim after an accident to recover the difference between your vehicle’s value immediately before the collision and its market value after repairs. Although New York has no specific statutory scheme for DMV claims, courts recognize them under general property-damage principles (see C.P.L.R. § 3017 (Notice and content of pleading)). Here’s how to calculate and document your loss:

1. Determine Pre-Accident Value

  • Use reputable pricing guides (e.g., Kelley Blue Book, NADA) to estimate fair market value (FMV) immediately before the accident.
  • Obtain dealership quotes or private-sale listings for similar make, model, year, mileage, and condition.
  • Retain printouts or screenshots showing date, mileage range, and listing details.

2. Gather Post-Repair Value Data

  • After completing repairs, re-evaluate FMV using the same pricing guides and comparable listings.
  • Note any lingering signs of damage (e.g., mismatched paint, panel gaps) that reduce value.
  • Keep photographs of repaired areas and any remaining imperfections.

3. Obtain a Professional Appraisal

  • Hire a qualified auto appraiser experienced in diminished value analyses.
  • Ensure the report addresses pre- and post-repair FMV, including market data and adjustment factors.
  • Request a signed, dated appraisal with the appraiser’s credentials and methodology.

4. Calculate Diminished Market Value

Subtract the post-repair FMV from the pre-accident FMV:

DMV = FMVbefore – FMVafter

For example, if your car was worth $15,000 pre-accident and $13,000 after repairs, your DMV is $2,000.

5. Document and Present Your Claim

  • Compile all evidence: repair invoices, appraisal report, pricing-guide printouts, and photographs.
  • Send a written demand to the at-fault party’s insurer, attaching your documentation.
  • Reference New York Insurance Law § 3420 (Prompt payment of claims) to support timely consideration.
  • If the insurer denies or undervalues your claim, consider Small Claims Court (up to $10,000) or consulting an attorney for a larger claim.

Helpful Hints

  • Act promptly: market values can fluctuate over time.
  • Use the same data sources for before/after valuations to maintain consistency.
  • Keep detailed repair and inspection records to show quality of repairs.
  • Photograph your vehicle from multiple angles before and after repairs.
  • Store all communications with insurers in writing—email or certified mail.
